Average IQ in Bangkok (Thailand): Estimates & Key Factors
Estimated Avg IQ
93
IQ Range
90–96
Region
Asia
Bangkok is Southeast Asia's largest economy outside of Indonesia and the region's premier business and logistics hub. The city captures a substantial urban premium over Thailand's national average through its concentration of educated professionals, international businesses, and Thailand's best universities including Chulalongkorn and Mahidol. Bangkok's international school sector is extensive, serving both expatriate families and affluent Thai professionals who seek English-medium education. However, a large service sector workforce with limited educational attainment moderates the city-wide average.
Important note: City-level IQ estimates are especially approximate. They reflect selection effects — cities attract educated, ambitious migrants — as well as local education quality, economic conditions, and available data. These figures do not reflect the intelligence or potential of any individual resident. For context on what IQ scores measure, see our guide to IQ.

Bangkok vs. Thailand National Average
Bangkok's estimate of ~93 sits above Thailand's national estimate of ~91, consistent with the selection effects large cities often show — educated, ambitious people migrating toward economic and cultural capitals.
Where This Number Comes From
No comprehensive IQ survey exists for Bangkok — or for almost any city. The figure above is an extrapolation: it starts from national-level estimates (compiled cross-national datasets such as Lynn & Vanhanen's, alongside PISA and TIMSS assessment data), then adjusts for the city's educational attainment and economic composition. Those national compilations are themselves debated in the academic literature, and a city-level extrapolation inherits all of that uncertainty and adds more. Treat the range shown above as an illustrative band, not a measured confidence interval.
Frequently Asked Questions
What is the average IQ in Bangkok?
Bangkok's estimated average IQ is around 93, noticeably above Thailand's national average of approximately 91. The city's concentration of educated professionals, international businesses, and elite universities creates a meaningful urban premium.
How does Bangkok compare to other Southeast Asian capitals?
Bangkok scores similarly to Kuala Lumpur and above Jakarta. Singapore is in a different league as a city-state with a uniquely high education system. Bangkok's strength lies in its role as the dominant economic hub of mainland Southeast Asia.
What factors limit Bangkok's average despite being a wealthy city?
Bangkok's large tourism and service sector employs many workers who migrated from rural provinces with limited formal education. This population, while valuable to the economy, has lower educational attainment than the professional class, moderating the city-wide cognitive average.
